Automotive industry

Marking solutions for the automotive industry must be reliably integrated into systems and provide the highest quality to ensure traceability.

What actually is marking?

Annealing

For colored annealing marking on metals, the laser beam heats up the workpiece to a certain temperature at the point where the marking is required. In the process, oxide layers are formed on the surface, the characteristics of which give a particular color impression.

Discoloration and foaming

For the coloring of plastics, the laser beam heats up the surface locally. Depending on the plastic, the workpiece becomes darker or lighter. For foaming, the laser melts the workpiece locally. Small bubbles form in the melt, increasing the volume and reflecting the light diffusely. This is why the processed area looks lighter than the surrounding material.

Engraving and ablation

During engraving, the laser beam ablates the material. A recess is created in the workpiece – the engraving. Ablation is understood to be the partial removal of top layers such as anodized aluminum or special laser marking films. These are applied to the base material and differ greatly in terms of color from this.
